Spray glue for infusion and RTM (polyester, vinylester and epoxy compatible) 500ml

Process benefits :

• High adhesion strengh with gelcoat, barrier-coat, glass fibre matting and fibreglass laminates;
• Full compatibility with polyester, vinylester and epoxy resins;
• Does no compromise the mechanical performance of laminates, even if used in higher quantities that actual requirements
• Does not weaken the degree of inter-laminar adhesion between the different layers of a laminate
• Contains a blue colorant which makes it possible to assess and regulate the quantity applied, the colour disappears during polymerization

Application

FX 51 must be sprayed by applying a uniform layer of adhesive on one or both the surfaces to be adhered.

The time required before PRO-FIX 51 develops its full adhesive strength is affected by the ambient conditions (ambient temperature, humidity, air flow over the surface being treated) and by the thickness applied, varying from 30 seconds to few minutes. High temperatures and good aire circulation encourage evaporation of the solvent phase and accelerate adhesive performance. Conversely, the application of high thickness of mateial (incated by an intense blue colouration), which might be required with heavy weight fabrics or very porous materials, slows the process.

After this period the fabric (or core material) can be positinned by ensuring that it adheres well to the surface, and the operation repeated for subsequent layers. The adhesive retains its repositionable characteristics for a few minutes after application of the reinforcement: the duration of this period varies in relation to the thickness of FX 51 applied, the temperature, ans the ambient conditions in general.

For aerosol application, hold the spray about 20 to 30 cm from the surface and spray an even film of adhesive onto one or both surfaces to be adhered.

The quantity of PRO-FIX 51 to be applied depends on the type of surface onto which it is sprayed and by the weight of the material to be adhered.

Smooth non-absorbent surfaces like gelcoat, barrier-coat or fibredlass moulds require small quantities of adhesive, while porous surfaces (e.g. expanded PVC and PU) or highly absorbent surfaces (e.g. chopped strand mat) require the application of greater volumes in order to achieve the required adhesion.

With the fibreglass materials most commonly used in the infusion process -bi-axial, combi, etc.) the average yield can be calculated at around 60 to 100m² with 1kg of PRO-FIX applied by using zn zir brush or similar system. An aerosl container is sufficient for the treatment of an average aera of 15 to 25m²
